Application filed August 5, 1914. Serial No. 855,217.

To all whom it may concern:

Be it known that I, JOHN BERNSTEIN, a subject of the King of Hungary,residing at Lewisburg, in the county of Union and State of Pennsylvania,have invented certain new and useful Improvements in Armor for InnerTubes of Pneumatic Tires, of which the following is a specification,reference being had therein to the accompanying drawing.

This invention relates to an armor for the inner tubes of pneumatictires and has for its object to provide a device of such class, in amanner as hereinafter set forth, to prevent the puncturing of the innertube of a pneumatic tire.

Further objects of the invention are to provide an armor for the purposeset forth which is simple in its construction and arrangement, flexible,resilient, strong, durable, comparatively light in weight, efficient inits use, conveniently set up with respect to the inner tube and outershoe of a tire, and comparatively inexpensive to manufacture.

With the foregoing and other objects in view the invention consists of anovel construction, combination and arrangement of parts as hereinaftermore specifically described and illustrated in the accompanyingdrawings, wherein is shown an embodiment of the invention, but it is tobe understood that changes, variations and modifications can be resortedto which come within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote correspondingparts throughout the several views, Figure 1 is a perspective View of aportion of a tire showing the adaptation thereto of my armor. Fig. 2 isa perspective view showing a por tion of the armor.

Referring to the drawings in detail 1 denotes a rim of a tire, 2 anouter shoe and 3 an inner tube.

An armor in accordance with this in-.

vention consists of a pair of annular members 4i, 5 which are adapted tobe interposed between the outer shoe 2 and inner tube 3 at apoint wherethe shoe is engaged by the clencher flanges 6 of the rim 1.

Copies of this patent may be obtained for five cents each, by addressingthe The member 4 is connected to the member 5 by thin resilient flexiblestrips 7 which are disposed transversely with respect to the inner tube3 and said strips are arched in contour and have a tendency wherebytheir ends will spring toward each other. The strips 7 may be made ofrubberized canvas, leather having the necessary elasticity, or very thinmetal. Each strip 7 carries a series of arrester members and each saidarrester member is formed from a thin piece of metal of necessaryelasticity and comprises a body portion 8 and a shank 9 formed with aseries of barbs 10 which are adapted to be passed through a strip 7 andbe clenched to the inner face of a strip. The shanks 9' of each seriesof arrester members are positioned upon the outer face of theirrespective strip and the body portions 8 of each series of arrestermembers project from its respective strip and over-lap the body portionsof a series of arrester members carried by adjacent strip. The seriesofar rester members of one strip are staggered with respect to thearrester members of adjacent strip. The arrester members are provided toarrest the passing of a nail, piece of glass or other sharp instrumentwhich may pass through the outer shoe and under such construction willprevent such nail, glass or sharp instrument puncturing the inner tube.

What I claim is:-

The combination with a pneumatic tire, of an internal armor comprising apair of side rings, flexible resilient arched strips extendingtransversely of the wheel and having their ends attached to said rings,a series of arrester members each having a shank formed with barbssecured by said barbs in each arched strip, and the adjacent series ofarrester members overlapping each other and arranged in staggeredrelation.

In testimony whereof I affix my signature in the presence of twowitnesses.

JOHN BERNSTEIN.
